Cerebras Systems, a US-based AI infrastructure company, has completed a $1.1bn Series G funding round, resulting in a post-money valuation of $8.1bn.
The round was led by Fidelity Management & Research and Atreides Management, with additional participation from Tiger Global, Valor Equity Partners, and 1789 Capital.
Existing investors Altimeter, Alpha Wave, and Benchmark also contributed to the funding. Citigroup and Barclays Capital acted as joint placement agents for the transaction.
Cerebras Systems intends to allocate the new capital towards further development of its AI processor technology, expansion of US manufacturing capacity, and scaling of its data centre infrastructure. The company stated that these initiatives are designed to address rising demand for its AI systems and services across multiple sectors.
Since launching its inference service in late 2024, Cerebras Systems reports sustained growth in both performance metrics and customer adoption.
The company claims it has consistently delivered inference speeds more than 20 times faster than Nvidia graphic processing units (GPUs) on a range of open-source and proprietary models over the past year. This performance differential has driven increased uptake among enterprises seeking real-time AI applications such as code generation, reasoning, and agentic workloads, said Cerebras Systems.
Its previous Series F round in November 2021 raised $250m at a valuation exceeding $4bn.
Cerebras Systems co-founder and CEO Andrew Feldman said: "From our inception we have been backed by the most knowledgeable investors in the industry. They have seen the historic opportunity that is AI and have chosen to invest in Cerebras.”
The company’s core technology includes the Wafer Scale Engine 3 (WSE-3), which it describes as the largest AI processor currently available. It is 56 times larger than the largest GPU and operates at lower power per compute unit.
Cerebras Systems claims to serve trillions of tokens per month through its own cloud platform, on-premises deployments, and partner ecosystems.
In 2025, AlphaSense, Amazon Web Services (AWS), Cognition, GlaxoSmithKline, IBM, Mayo Clinic, Meta, Mistral, Notion, the US Department of Energy, and the US Department of Defense have adopted Cerebras Systems’ hardware for AI workloads.
Individual developers are also using Cerebras Systems via platforms like Hugging Face.
In September 2025, Cerebras Systems announced a partnership with Carahsoft Technology. The aim of the partnership is to extend its AI inference solutions into federal, state and local government agencies as well as educational institutions through Carahsoft’s distribution network.
